Accumulation as a major factor in four bush levels (10, 13.3, 20 and 40) in square meter and Nitrogen fertilizer divisgon in three levels (20-100-30), (50-50-50), (50-70-30) kg/ha were investigated. The results indicated that bush accumulation affected seed and biolgie function, number of capsul in bush, number of capsul in bush, number of foliage and height the effect of nitrogen fertilizer division is on seed function, biologic function, seed weight, number of capsul in bush, number of seed in capsul, number of secondary foliage and height. Average of nitrogen fertilizer comparison indicated that the highest seed function by 1727 kg/ha was obtained in division (50-50-50) kg/ha in pure nitrogen. Bush accumulation comparison indicated that the most seed function (1912 kg/ha) was achieved in accumulation of 40 bushes/m2. The mutual effects of bush accumulation and nitrogen fertilizer division showed that most seed function as 2044 kg/ha was in accumulation of 40 bushes/m2 and with usage of (50-50-50) pure nitrogen in kg/ha.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83534

A factorial experiment was performed based on RCB olesign with three replications. The treatments were row spacing at three levels: 20, 25 and 30 cm and four nitrogen fertilizer rates: 0.7, 1.0, 1.3 and 1.6 R from urea source, based on soil testing and soil and water research institute recommendation. The R factor was 140 kg urea/ha. In this research work, some important agronomical traits such as number of pods per main stem, number of pods per auxiliary branches, number of pods plant, number of seeds per main pod, number of seeds per auxiliary pod, number of seeds per pod, 1000 seed weight, grain yield, oil percent and oil yield were studied. The results of analysis of variance showed that non significant differences exist between row spacing for grain yield. However, row spacing of 20 cm was relatively superior with an average grain yield of 1908 kg/ha. Interaction between row spacing and nitrogen rate on grain yield was non significant. Fertilizer rate of 1.6 R and row spacing of 20 cm with average 2291 kg/ha had maximum grain yield. Interaction between row spacing and nitrogen rate on oil yield was non significant but row spacing of 20 cm and fertilizer rate of 1.6 R showed maximum oil yield.

It was done by using a factorial experiment based on CRBD with four replications. Different developmental stages of maize include 50% emergence, transition from vegetative to reproductive stage, pollination and physiological maturity, plant height and stem diameter in transition stage, dry weight of various organs, yield and yield components and harvest index were studied. With increasing row spacing, stem dry weight in the pollination and physiological maturity, seed weight, grain yield, harvest index and grain number per ear significantly increased. Increasing plant density, leaf dry weight in transition, opening pollination and physiological maturity, stem dry weight in stages pollination and physiological maturity, ear dry weight and grain yield under the effect of density was studied and other traits plant density was not affected. The interaction between row spacing and plant density on stem dry weight in physiological maturity stage, stem diameter in opening pollination stage and grain yield were significant. Finally, knowing that with annual tests can not be a recommendation, but the results may be based on 75 cm row spacing with a density of 8 plants per square meter for the production of maize Sc 711 under conditions similar to this experiment can be recommended.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83534

Characters including yield, the number of fruit, plant high, were measured and examined during this experiment. The results showed that different substrates significantly affected many measured characteristics as follows: peat moss with 2998 grof fruit weight had the highest yield and leca with 355 grof fruit weight had the lowest yield between the whole treatments. And also between the treatments, peat moss with 54 numbers of fruit per pot had the most fruit number and leca with less than 8 fruit number per pot had the least number of fruit averagely. Peat moss with the average of 179 cm had the highest high and leca with 56.5 cmhad the lowest high between the substrates. The results also showed that the mixed perlite made some changes in the most measured characters in substrates compared to the pure one.

The main goal of this research was determining the suitable quantity and kind of nitrogen application to reach the maximum grain yield and oil yield of two sunflower cultivars in climatic conditions of Arak as provincial center of Markazi province. The experiments was done with different treatments of nitrogen and nitrogen coated urea each in 3 levels (25, 50, 100 kg/ha) of recorded cultivar and Liza–R–M hybrid based on factorial experiment in RCB with four replications. Some of compared characteristics were considered as, plant height, hay yield weight, head diameter, disk seed weight, 1000 seed weight, seed yield, harvest index, oil percentage, oil yield and rate of crop growing. The result of experiment showed that application of different nitrogen levels had significant difference on the rate of growing but the oil percentage had no differences. The highest grain yield was related to record cultivar with average 3.36 ton/ha and the treatment of 100 kg/ha nitrogen coated urea with average 3.96 ton/ha. The comparison of different treatments showed the highest increase in the crop growth rate in treatment of 100 kg/ha nitrogen coated urea much more than the others.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83534
